Automated Central Kitchen Packaging Line for Potato, Carrot and Chicken Portions

A customized multi-ingredient weighing and premade pouch packaging solution designed for cooked food processing, delivering consistent ingredient portions, accurate weighing and packaging speeds of up to 40 bags per minute.

Automated Packaging for Central Kitchen Operations

As central kitchens continue to expand their prepared meal production, maintaining consistent ingredient portions while increasing packaging efficiency has become an important part of daily operations.

For cooked and diced ingredients, manual portioning can be time-consuming and difficult to standardize. Different ingredients also have different shapes, textures and feeding characteristics, making accurate multi-ingredient weighing more challenging.

To address these requirements, TOUPACK developed an automated weighing and packaging line for a central kitchen application. The system handles three cooked ingredients independently:

• Cooked potato cubes: 10g per pack
• Diced carrots: 20g per pack
• Cooked chicken chunks: 60g per pack

Each ingredient is weighed separately and combined into one premade pouch, giving a total target weight of 90g per pack.

The complete line achieves a weighing accuracy of approximately ±1–2g and a packaging speed of up to 40 bags per minute.

Complete Multi-Ingredient Weighing and Packaging System

The production line integrates three 14-head screw combination weighers, a tray-type elevator, a rotary premade pouch packaging machine and an automatic checkweigher.

Main equipment configuration:

The three weighing systems work independently, allowing each ingredient to be measured according to its preset target weight before being delivered into the same package.

This configuration helps central kitchens manage multiple ingredients within one automated packaging process.

Three Independent 14-Head Screw Combination Weighers

The core of this packaging line is its three 14-head screw combination weighers.

Unlike conventional weighing systems designed mainly for free-flowing products, screw feeding is particularly useful when handling cooked diced ingredients that require more controlled feeding.

Each weighing system is assigned to one ingredient:

Weigher 1 – Cooked Potato Cubes

Target weight: 10g

The screw feeding mechanism provides controlled material delivery, helping maintain stable feeding and accurate small-portion weighing.

Weigher 2 – Diced Carrots

Target weight: 20g

The independent weighing system measures the carrot portion separately, helping maintain consistency between packages.

Weigher 3 – Cooked Chicken Chunks

Target weight: 60g

The screw feeding design supports controlled feeding of cooked chicken chunks, reducing reliance on manual portioning.

With three independent weighing systems, the line can handle different target weights and ingredient characteristics within one production setup.

Automatic Material Transfer and Premade Pouch Packaging

After weighing, the three ingredients are transferred through the material handling system and combined before entering the packaging machine.

The tray-type elevator supports automatic material transfer, reducing repetitive manual handling between the weighing and packaging stages.

A rotary premade pouch packaging machine then completes the main packaging operations:

1. Automatic pouch feeding
2. Pouch opening
3. Ingredient filling
4. Bag mouth positioning
5. Heat sealing
6. Finished pouch discharge

The rotary packaging structure supports continuous operation and coordinated filling and sealing, helping the central kitchen maintain a stable production rhythm.

The use of premade pouches also provides flexibility for different packaging materials and pouch styles, depending on the customer's product and packaging requirements.

Automatic Checkweighing for Finished Packages

After sealing, finished packages pass through an automatic checkweigher for weight inspection.

This final inspection stage helps identify packages that fall outside the configured weight limits and provides an additional quality control step before products move to the next stage of production.

For central kitchens supplying restaurants, catering businesses and food distribution channels, consistent package weight is important for portion control, production management and product standardization.

Combining multi-ingredient weighing with finished-package inspection creates a more controlled packaging process from ingredient dosing to final product checking.

Key Performance and Project Specifications

The central kitchen packaging line is designed around three ingredient portions and a target production speed of 40 bags per minute.

Actual production performance may vary depending on ingredient condition, feeding stability, pouch specifications and operating conditions.

Why Choose an Automated Multi-Ingredient Packaging Line?

For central kitchens and prepared food manufacturers, this type of integrated packaging solution offers several practical advantages.

Independent Ingredient Portioning

Three separate weighing systems allow each ingredient to be controlled independently, making it easier to maintain the required recipe proportions.

Consistent Portion Control

Automated weighing reduces dependence on manual portioning and helps improve consistency between packages.

Reduced Manual Handling

Automatic material transfer, weighing, filling and finished-package inspection reduce repetitive manual operations throughout the packaging process.

Integrated Production Workflow

The weighing systems, elevator, rotary pouch packaging machine and checkweigher work together as one coordinated production line.

Flexible Configuration

The weighing targets and packaging specifications can be configured according to the customer's product requirements, ingredient characteristics and production capacity.
